Okay, so we pretty much know that Apple is expected to announce the iPhone 5 on Wednesday evening, but now we have official, official confirmation from the Cupertino-based company, thanks to a slip up on its own search results on Apple.com.

Eagle-eyed readers of 9to5mac.com have spotted that searching for iPhone 5 on Apple's own site brings up a number of search results for the phone, even though Apple hasn't as announced it officially yet.

Apple isn't the first company to fall foul of its own website spilling the beans. Microsoft's website jumped the gun at E3, the gaming trade show, for the launch of the Kinect in 2011 - an hour before the event was about to start.

UPDATE Oh dear, more playing by Pocket-lint with the Apple search page revealing more products that Apple is waiting to launch. We can reveal that Apple will also announce a new iPod nano, and iPod touch, and a new version of iTunes as seen in the search results we've just grabbed from the Apple.com site.

And the searches continue. Now we've found a page called iPhone LTE, confirming the iPhone 5 will have LTE, something that we suggested would be the case in August, but now apparently confirmed by the listing.
